Overview
The recent discovery of a significant vulnerability in TeleControl Server Basic has prompted a widespread call for immediate action to mitigate potential risk. Identified as CVE-2025-32830, this vulnerability poses a substantial threat to all versions of TeleControl Server Basic preceding V3.1.2.2. The vulnerability is a SQL injection point, allowing a malicious actor to bypass authorization controls, manipulate the application’s database, and execute code with ‘NT AUTHORITYNetworkService’ permissions.
Given the severity of this exploit and its potential for system compromise or data leakage, it is crucial to understand the nature of this vulnerability, the risks it presents, and the steps necessary to patch the vulnerability or implement temporary mitigation measures.
Vulnerability Summary
CVE ID: CVE-2025-32830
Severity: High (CVSS:8.8)
Attack Vector: Network
Privileges Required: Low (Authenticated Access)
User Interaction: None
Impact: System Compromise and Potential Data Leakage
Affected Products
Product | Affected Versions
TeleControl Server Basic | All versions < V3.1.2.2 How the Exploit Works
The CVE-2025-32830 vulnerability exists due to an insecure coding practice in the ‘UnlockProject’ method used internally by TeleControl Server Basic. This method fails to properly sanitize input, allowing a remote attacker to inject malicious SQL statements. The attacker must have authenticated access and be able to reach port 8000 on the target system.
Upon successful exploitation, the attacker can bypass authorization controls, read from and write to the application’s database, and execute code with ‘NT AUTHORITYNetworkService’ permissions. This could potentially lead to system compromise and data leakage.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited using a HTTP POST request to inject a malicious SQL payload:
POST /UnlockProject HTTP/1.1
Host: target.example.com:8000
Content-Type: application/json
{ "project_id": "1; DROP TABLE users;" }In this example, the malicious SQL command `DROP TABLE users;` is appended to a legitimate `project_id` value. If the server executes this payload, it could result in the deletion of the ‘users’ table from the database.
Mitigation Guidance
It is recommended that users of TeleControl Server Basic immediately update their software to version V3.1.2.2 or later. If updating is not immediately possible, users should consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure to detect and block attempted exploits of this vulnerability.
